Re: How many fields can SOLR handle?
RoySolr, Not sure what language your client is written in, but this is a simple if statement. if (category == TV) { qStr = q=*:*facet=truefacet.field=tv_sizefacet.field=resolution; elseif (category == Computer) { qStr = q=*:*facet=truefacet.field=cpufacet.field=gpu; } curl http://localhost:8983/solr/select?; + qStr; On Thu, Jul 7, 2011 at 2:29 AM, roySolr royrutten1...@gmail.com wrote: Hello Erik, I need the *_facets also for searching so stored must be true.

Re: How many fields can SOLR handle?
Yes i use something like that. I make a db connection to get the facets for the chosen category. With this data i add facet.fields dynamically: example: foreach(results as result){ qStr = facet.field= . result; } I was searching for a solution that i don't need to get the facets from db. Now i cache this list(PHP) so i don't need a request every time to the db.

Solr currently cannot do this automatically.

Re: How many fields can SOLR handle?
Hi, I know i can add components to my requesthandler. In this situation facets are dependent of there category. So if a user choose for the category TV: Inch: 32 inch(5) 34 inch(3) 40 inch(1) Resolution: Full HD(5) HD ready(2) When a user search for category Computer: CPU: Intel(12) AMD(10) GPU: Ati(5) Nvidia(2) So i can't put it in my requesthandler as default. Every search there can be other facets. Do you understand what i mean? -- View this message in context: http://lucene.472066.n3.nabble.com/How-many-fields-can-SOLR-handle-tp3033910p3139833.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: How many fields can SOLR handle?
This is taxonomy/index design... One way is to have a series of fields by category: TV - tv_size, resolution Computer - cpu, gpu Solr can have as many fields as you need, and if you do not store them into the index they are ignored. So if a user picks TV, you pass these to Solr: q=*:*facet=truefacet.field=tv_sizefacet.field=resolution If a user picks Computer, you pass these to Solr: q=*:*facet=truefacet.field=cpufacet.field=gpu The other option is to return ALL of the fields facet'd, but this is not recommended since you would certainly have performance issues depending on the number of fields.

Re: How many fields can SOLR handle?
Thanks Bill, That's exactly what i mean. But first i do a request to get the right facetFields from a category. So a user search for TV, i do request to a db to get tv_size and resolution. The next step is to add this to my query like this: facet.field=tv_sizefacet.field=resolution. I thought maybe it's possible to add the FACET fields automatically to my query(based on category). I understand this isn't possible and i need to do first a request to get the facet.fields. -- View this message in context: http://lucene.472066.n3.nabble.com/How-many-fields-can-SOLR-handle-tp3033910p3139921.html Sent from the Solr - User mailing list archive at Nabble.com.

Re: How many fields can SOLR handle?
Hi! I can't help you with the question about the limit to the number of fields. But until now I haven't read anywhere that there is a limit. So I'd assume that there is none. For your second question: Another question: Is it possible to add the FACET fields automatically to my query? facet.field=*_FACET? Now i do first a request to a DB to get the FACET titles and add this to the request: facet.field=cpu_FACET,gpu_FACET. I'm affraid that *_FACET is a overkill solution. You can add parameters automatically (as defaults) to your requests. Look into the solrconfig.xml file for requestHandler that handles your requests. (In the example it's the one starting requestHandler name=search class=solr.SearchHandler default=true). There is a lst name=defaults where you can add as many request parameters as you like. Is that what you're talking about? On Mon, Jul 4, 2011 at 13:44, roySolr royrutten1...@gmail.com wrote: Nobody?
